SPECIFICATION forming part of Letters Patent No. 794,876, dated July 18,1905.

Application filed n ary 5, 1904- Serial No. 187,819.

To all whom it may concern.-

Be it known that I, EDGAR S. MoUL'roN,a citi- Zen of the United States,residing at Central City, in the county of Grilpin and State ofColorado, have invented certain new and useful Improvements in Ore orRock Crushers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in ore or rock crushers.

The object of the invention is to construct a machine which will crushdamp or wet ore with the same proficiency as when crushing dry ore orrock.

Another object of the invention is to construct a crusher having a fixedmember and an oscillating cushioned member and means for the adjustmentof said oscillating member.

Another object of the invention is to construct a device which isprovided with a fixed jaw and an oscillating jaw cooperating therewith,said oscillating jaw assembled with means whereby the said jaw when inoperation produces a rounding crushing action upon the materialdeposited between the fixed jaw and the oscillating jaw.

An additional object is the construction of a machine whichwillautomatically be thrown out of operation when a foreign object, such asa piece of steel, is placed between the fixed and moving members of themachine.

With these and other objects in view the invention consists in the novelconstruction, combination, and arrangement of parts, as will behereinafter fully described, illustrated in the accompanying drawings,and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of the machine shownpartly in longitudinal section. Fig. 2 is a rear elevation of themachine. Fig. 3 is an elevated front view of a mechanism constructed inaccordance with the present invention.

Referring to the drawings by reference-numerals, 1 indicates a casing orframework of Upon the forward end of the the machine.

also to-assist in holding the crusher together.

A plurality of crushing-plates are arranged in an assembled positionwith said buti'etingblock and consistsin upper, middle, and lowerplates, which are employed in the construction of a fixed crusher-jaw.Said crushingplates 6, 7, and 8 are retained in position by means ofcheek-plates 9, secured in position upon the machine near each sidethereof. A longitudinal rotary eccentric-shaft 10 is journaled' upon theupper portion of the casing 1 and extends in a transverse position tosaid casing. Said shaft 10 is retained in a fixed position by means ofremovable caps 11, secured upon the side boxes of the machine. Upon eachend of the eccentric-shaft 10 are keyed balance or fly wheels 12, one ofwhich is provided with an annular flange 13, which is secured to saidwheel 12 for the purpose of receiving a suitable belt, whereby motionmay be imparted to the crusher. Keyed upon the eccentric-shaft 10 is aneccentric 141.

In the construction of the machine a jaw 15 is employed, said jawcomprising a lever member 16, which is mounted upon the eccentric 1 1,keyed to the eccentric-shaft 10. Upon the upper portion of the levermember 16 is a removable box 17, which is adapted to engage theeccentric 14, keyed to the shaft 10. To facilitate the operation of themachine, and particularly for the purpose of taking up the wear of thebox 17, a wedge-key 18 is employed. It will be obvious as the block 17is worn away the wedge-key 18 can be driven inward, and thereby causethe block 17 to be forced against the periphery of the eccentric 14.Removably mounted upon the surface of the lever member 16, which isadapted to face the fixed jaw, is a plurality of assembledcrushing-plates 19, 20, and 21, which are retained in position by meansof bolts or suitable rivets 22. The inner face of the lever 16, whichcarries the crushing-plates 19, 20, and 21, is angular in shape and isprovided with an integral projection 23, which assists in supporting thelower plate 21, which is secured to the oscillating jaw 15 in a planedifferent from that of the remaining crushing-plates employed in theconstruction of the oscillating jaw.

An adjusting mechanism is provided for the oscillating jaw and is anessential feature of the invention. The adjusting mechanism comprises inits construction a plurality of longitudinal adjustable bolts 24, whichare secured upon each side of the casing 1 by means of a transverseremovable plate or bar 26, preferably constructed of steel. Said bar 26is of sufficient length to project beyond each side of the casing, andto the projecting ends thereof the bolts 24 are removably secured. Eachof the bolts 24 is provided with integral annular extensions or loops25. Owing to the construction of bolts 24 and transverse plate 26, theoscillatory jaw is provided with a cushioning mechanism, as it will beobvious that if suflicient pressure is brought to bear upon theoscillatory jaw a slight movement of the lower end thereof in alongitudinal plane will be produced, owing to the fact that the plate 26is of sufiicient resiliency to permit of the ends thereof to be slightlybent by means of the pressure exerted thereon through the medium ofbolts 24. A plurality of adjustingnuts 27 are mounted upon the bolt 24and are adapted to engage the member 26 for retaining the bolts 24 in anadjusted position. An auxiliary or secondary adjusting-bolt 28 issecured upon the rear portion of the machine, and if it is desired aplurality of these bolts 28 may be secured in an assembled position forthe purpose of assisting in adjusting the oscillating jaw or coactingwith the lever-bolts 24 in the adjustment of said oscillating-jaw 15.The inner end of the member 28 is adapted to engage a plate or member29, which abuts one of the squared surfaces of the integral extension ofthe bolts 24. It will be obvious that a plurality of members 29 may besecured in a parallel position, if-

preferred, in the construction of the crusher. Within each of theannular extensions or loops 25 of the bolt 24 is removably mounted a box30. Within said box 30 is journaled a shaft 31, and upon said shaft 31and between the boxes 30, carried within the extensions 25 of the bolts24, is a friction-roller 32. It will be apparent upon considering thedrawing Fig. 1 that a suitable aperture is formed within each side ofthe casing 1 for the purpose of permitting of the insertion of theroller 32 in an assembled position within the machine. Upon the surfaceof the lever member 16 opposite to that to which the crushingplates 19,20, and 21 are secured is a removable plate 33, which is held in a fixedposition roller 32 and is so constructed, as heretofore described, thatwhen the same has become worn it can be easily removed and a-new platepositioned upon the oscillating jaw 15. To normally retain the lower endof the oscillating jaw in engagement with the roller 32, an

I which is provided with an annular extension formed integral therewithat one of its ends member 40, which in this instance is shown in thedrawings as a helical spring. Said spring or cushion member 40 issecured to a member 41, constructed similarly to said member 39. Themember 41 is removably mounted upon the integral extension of theoscillating jaw 15. The cushioning member will normally retain the lowerend of the oscillating jaw 15 in contact with the regulating-roller 32and will also permit of the oscillating jaw to move toward the fixed jawand also permit of a slight downward movement and will retain the jaw atall times in contact with the adjusting mechanism. It will be apparentthat by adjusting the bolts 24 and the auxiliary bolts 28 the spacing ofthe oscillating jaw with respect to the fixed jaw can be easilyobtained.

The two jaws provide in combination with the cheek-plates a hopper orreceptacle for the ores or rock which is to be crushed, and tofacilitate the depositing of the materials between the fixed and movablejaws a suitable shield 42 is secured above the jaws and in such aposition as to conduct the materials which are to be crushed to thecompartment formed between the said jaws.

A shield 42 is mounted upon the casing 1 above the stationary and movingjaws, said shield 42 comprising in its construction a casing having aback and integral side portions, which are adapted to be mountedadjacent to the upper edges of the jaws and cheek-plates 9. Said shieldis constructed for the purpose of preventing any foreign substances frombeing discharged over the upper edges of the jaws when said material isbeing supplied to said members.

In the operation of the machine the eccentric shaft 10 is rotated insuch a manner as to I cause the oscillating jaw 15 to move from right toleft. This throws the said jaw toward the fixed jaw and downward in onestroke. The

The movement of the oscillating jaw gives a rolling movement to thematerial being worked toward the outlet between the faces. As the shaftcontinues its revolution the moving jaw is withdrawn, raised, and againforced against the stationary face and downward. At each revolution itcrowds out the material that has been crushed and allows fresh materialto fall into the compartment formed between the fixed and moving jaws.Without this expelling movement wet and sticky material would pack atthe narrow bottom of the opening and neither go through itself or permitanything else to pass from between the jaws. Another advantage of theconstruction as set forth in the foregoing description is that theoperation of the lower portion of the moving jaw against the roller 32increases the leverage of the eccentric at the point where it is mostneeded in the operation of the crusher.

While this crusher exerts as powerful a leverage as any now in the art,it is a peculiar.

fact that it cannot be injured by dropping a hammer-head or any foreignmetallic substance between the jaws while the said ma chine is inmotion. The injuring of the machine by the depositing of a piece ofsteel or the like within the hopper formed by the jaws is one of thedisadvantages in the machines known in the patented art. When suchforeign objects are deposited between the jaws, the natural results ofsuch operation are the breakage of a portion of the crusher. In mymachine I have found by actual experience that the machine merely stopsafter one or two labored revolutions. The wooden buifetingblock gives aresilient or cushioned effect to the crushing-jaws,and when the machineis in operation this buifeting-block produces a machine which iscomparatively noiseless in operation.

The machine can be run with a small loose belt, which permits of themachine being thrown out of operation when non-breakable material, suchas a steel hammer-head, is inserted between the jaws, for the reasonthat a loose belt will throw itself free from the belt-pulley or annularflange 13, secured to one-of the fly or drive wheels 12.

In this machine the movable crushing-jaw has a forward, downward, andupward movement, said movement being greatly facilitated by theassembling with said jaw of cushion means. Another essential element ofthe machine is the arrangement with the moving jaw of means for theadjustment of said jaw relative to the position of the fixed jaw. Owingto the angular crushing face of the movable jaw, the rolling movement ofsaid jaw relative to the material that is to be crushed is obtained.

It will be apparent from the foregoing description that certainalterations, modifications, and changes may be made in the constructionof a machine in accordance with my invention, and I therefore reservethe right to make such changes, alterations, and modifications as shallfairly fall within the scope of my invention,
